DP-SPW1116 20-Inch Surface Cleaner for Loading Docks and Commercial Pads

The DP-SPW1116 spins a 20-inch stainless steel disc rated to 4350 PSI, a path sized to clear commercial parking pads and dock aprons in fewer passes than a 15- or 18-inch head. Dual rotating nozzles hold an even spray across the full arc, so concrete comes out without the streak lines a wand leaves. Four 360-degree casters and dual handles keep the head tracking straight on flat surfaces.

DP-SPW1116 Coverage and Connection

  • 20-inch cleaning disc — covers large flat pads faster, trimming labor time on open concrete and asphalt.
  • 4350 PSI rated pressure — accepts high-output commercial gas pressure washers; run it with a machine of 2500 PSI or higher.
  • Dual rotating nozzles — spread pressure evenly across the 20-inch arc to eliminate streak lines.
  • Two hose adapters plus 3/8" QC inlet — M22 and quick-connect fittings match most gas and electric pressure washers with no extra parts.
  • Four 360-degree casters — maintain steady nozzle standoff and steer around obstacles on flat surfaces.
  • Splash-free skirt — a circular brush keeps overspray and debris contained around the head.
  • Stainless steel construction — holds up to repeated daily use without corroding.

DP-SPW1116 Applications and Environments

Pressure washing contractors run the DP-SPW1116 on parking lot and loading dock contracts where the 20-inch disc shortens job time on large concrete pads. Municipal public works crews clean transit platforms, plaza pavers, and public walkways during off-peak hours where wide-path efficiency keeps the job inside its maintenance window. Facility managers use it on machine-pad foundations and truck wash lanes between service cycles. Restaurant exterior services clean grease-pad areas and dumpster enclosure concrete where thorough coverage in minimum passes keeps the site up to code. The splash-free skirt contains overspray on occupied sites, and matching the unit to a pressure washer at or above 2500 PSI keeps the nozzles rotating at full speed across the width.

Frequently Asked Questions

How much faster is a 20-inch surface cleaner than an 18-inch on a commercial parking lot?
A 20-inch path provides 23% more coverage per pass than an 18-inch path (20² vs 18²). On a 10,000 sq ft parking lot, this reduces total pass count from approximately 111 to 90 passes — saving roughly 15–20 minutes per job at standard cleaning pace.
What pressure washer output is needed to run the DP-SPW1116 at full capacity?
At 4350 PSI, the DP-SPW1116 is designed for commercial gas pressure washers producing 3.0–4.0 GPM. Confirm your pressure washer's PSI and GPM ratings meet both the maximum pressure and minimum flow requirements before use.
Is a 20-inch surface cleaner suitable for residential driveways?
Yes, but the wider path is harder to maneuver in tight driveway borders, around pillars, and near building foundations than a 15-inch model. For residential driveways under 20 feet wide, the 15- or 18-inch models offer better maneuverability without meaningfully more cleaning passes.
What is the difference between hose adapters and extension wands?
Hose adapters change the connection fitting size to match your pressure washer outlet. Extension wands add physical length between the gun and surface cleaner. The DP-SPW1116 includes hose adapters for connection compatibility; it does not include extension wands.
Can the DP-SPW1116 clean oil-contaminated concrete?
Surface cleaners distribute pressure evenly but do not apply chemical cleaning agents. For oil contamination, apply a degreaser or concrete cleaner to the surface for 5–10 minutes before running the surface cleaner to lift oil that high pressure alone cannot remove.
How does the rolling wheel base affect cleaning on uneven surfaces?
The wheel base maintains the nozzle heads at a consistent height above flat surfaces. On cracked or uneven concrete, the nozzle height varies over low and high points, creating slight pressure variation. For severely uneven surfaces, manual wand washing maintains more consistent standoff distance.
What maintenance does the dual nozzle assembly require?
After each use, flush with clean water to clear detergent and mineral deposits. Inspect the O-rings at the swivel joint for wear annually. Worn nozzle orifices produce oval rather than circular spray patterns, causing streak lines — replace nozzle tips when pattern deviation is noticeable.
